About the 15 Puzzle
The timeless sliding-tile puzzle. A grid of numbered tiles has one empty space; click or tap any tile next to the gap to slide it in. Keep sliding until the numbers are back in order, with the blank in the last corner. Every puzzle is shuffled by random legal moves, so it is always solvable. Choose 3×3 for a quick warm-up, 4×4 for the classic fifteen puzzle, or 5×5 for a real challenge. It runs in your browser — no signup, no download.
